How do I know whether this is a function or not? And can someone EXPLAIN the steps on how to determine on how it would be a function please?

Answers

Answer:

Yes

Step-by-step explanation:

A function would be f(x), a output for each x input.

The slope intercept form is y - mx + b! *keep this in mind*

If you graph this as well, it would be easier to see if its a function too. If the line crosses through it once, it is indeed a function. If it doesn't, it isn't

Answer: A) m = 9, n = 9

==========================================================

Explanation:

This is a 45-45-90 right triangle. Any triangle of this form is isosceles, where the two legs are the same length. In this case, m and n are those two legs. So m = n.

We can then apply the Pythagorean theorem to say

a^2 + b^2 = c^2

m^2 + n^2 = (9*sqrt(2))^2

m^2 + m^2 = 9^2*(sqrt(2))^2

2m^2 = 81*2

m^2 = (81*2)/2

m^2 = 81

m = sqrt(81)

m = 9

As a shortcut, the hypotenuse of a 45-45-90 triangle is equal to sqrt(2) times the length of either leg. If m is the length of the leg, then m*sqrt(2) is the length of the hypotenuse. So in a sense, we take this thought process backwards to go from a hypotenuse 9*sqrt(2) to a leg length of 9.

Which expression is equal to (7 * 2) 2?

A)(7 + 2) × 2
B)(2x2)+7
C)7x(2 x 2)
D)(2 x 7) + (2x2)

Answers

Answer:

C. 7 * (2 * 2)

Step-by-step explanation:

Figure out the original expression to see the equivalent expression.

(7 * 2) * 2

14 * 2

We have to look for an expression that equals 28.

A is (7 + 2) * 2.

(7 + 2) * 2

9 * 2

A equals 18, so it's not equivalent to the original expression.

Now B, which is (2 * 2) + 7

(2 * 2) + 7

4 + 7

B equals 11, so it is also not equivalent.

Now C; that is 7 * (2 * 2)

7 * 4

C equals 28, so that is equivalent. Although we have found our answer, we need to make sure it's right by evaluating D. ((2 * 7) + (2 * 2))

(2 * 7) + (2 * 2)

14 + 4

D, like A, equals 18, so it is also incorrect.

C is the only expression that is equivalent to (7 * 2) * 2, so it is the answer.

What is the value of x in the solution to the system of equations below?
15x - 12y = 13

30x + 9y = 4

Answers

Answer:

1/3

Step-by-step explanation:

Use the elimination method.

15x - 12y = 13

30x + 9y = 4

If you add both equations you will not cancel out any variables, so you need to multiply one of the equations by something. Multiply the first equation by -2 to cancel out the x values.

-2(15x - 12y = 13)

30x + 9y = 4

You should have these two equations now:

-30x + 24y = -26

30x + 9y = 4

Add them together now. You should get this now.

33y = -22

Divide both sides by 33. You should get y = -2/3

Now, substitute the y value into any of the two equations that you started with. Let's substitute the y value for the second equation.

30x + 9 (-2/3) = 4

30x - 6 = 4

30x = 10

30 30 (divide 30 and 10 by 30)

x = 1/3

Rectangle ABCD has a width of 8 yards and a length of 20 yards. Rectangle QRST, which is similar to rectangle ABCD, has a length of 40 yards.
Find the scale factor of ABCD to QRST and the perimeter of each rectangle.

Answers

Answer: 16 yards would be your answer

The scale factor of ABCD to QRST is 1:2

The perimeter of rectangles ABCD and QRST are 56 yards and 112 yards respectively.

Rectangle ABCD has a width of 8 yards and a length of 20 yards.

Rectangle QRST is similar to rectangle ABCD.

Rectangle QRST has a length of 40 yards.

Scale factor:

Therefore, the scale factor of ABCD to QRST can be calculated as follows:

let

x = width of rectangle QRST

8 / x = 20 / 40

8 / x = 1 / 2

x = 16

The scale factor of ABCD to QRST is 1:2

Perimeters

perimeter ABCD = 2(8 + 20) = 56 yards

perimeter QRST = 2(16 + 40) = 112 yards.
